Book Synopsis Free-flight-tunnel Investigation of Dynamic Longitudinal Stability as Influenced by the Static Stability Measured in Wind-tunnel Force Tests Under Conditions of Constant Thrust and Constant Power by : Robert O. Schade
Download or read book Free-flight-tunnel Investigation of Dynamic Longitudinal Stability as Influenced by the Static Stability Measured in Wind-tunnel Force Tests Under Conditions of Constant Thrust and Constant Power written by Robert O. Schade. This book was released on 1950. Available in PDF, EPUB and Kindle. Book excerpt: An investigation has been conducted to determine the dynamic longitudinal stability as influenced by the static stability measured in wind-tunnel force tests under conditions of constant thrust and constant power. The amount of static stability was varied in flight tests by changing the power applied to a pusher propeller with an offset thrust axis and by shifting the center of gravity of the model.

Book Synopsis A Wind-tunnel Test Technique for Measuring the Dynamic Rotary Stability Derivatives Including the Cross Derivatives at High Mach Numbers by : Benjamin H. Beam
Download or read book A Wind-tunnel Test Technique for Measuring the Dynamic Rotary Stability Derivatives Including the Cross Derivatives at High Mach Numbers written by Benjamin H. Beam. This book was released on 1955. Available in PDF, EPUB and Kindle. Book excerpt: A method is described for measuring the dynamic stability derivatives of a model airplane in a wind tunnel. The characteristics features of this system are that single-degree-of-freedom oscillations were used to obtain combinations of rolling, yawing, and pitching motions; that the oscillations were excited and controlled by velocity feedback which permitted operation under conditions unfavorable for more conventional types of oscillatory testing; and that data processing was greatly simplified by using analog computer elements in the strain-gage circuitry.

Book Synopsis A Wind-tunnel Evaluation of Analytical Techniques for Predicting Static Stability and Control Characteristics of Flexible Aircraft by : Irving Abel
Download or read book A Wind-tunnel Evaluation of Analytical Techniques for Predicting Static Stability and Control Characteristics of Flexible Aircraft written by Irving Abel. This book was released on 1972. Available in PDF, EPUB and Kindle. Book excerpt: An experimental evaluation of analytical techniques for predicting certain stability and control characteristics of a large flexible aircraft is presented. Analytical methods based on both the model approach and flexibility influence coefficients are developed to predict the aerodynamic characteristics of a flexible airplane. These methods are then applied to a flexibly scaled model of a supersonic transport configuration. Comparisons of wind-tunnel data, calculations based on the model approach, and flexibility influence coefficients are presented over the Mach number range from 0.6 to 2.7. An examination of the results obtained from this study indicates that both analytical techniques predict reasonably well the effect of flexibility on the basic longitudinal characteristics and that both techniques give generally comparable results.
